ARIA!) POLANSKY, OF DOUGLASTOWN, NEW YORK.

COMBINATION CARPET AND WINDOW CLEANER.

T 0 all whom it may concern Be it known that I, ARPAD POLANSKY, citizen of Hungar residing at Douglastown,

in thecounty 0 Flushing and State of New York, have invented certain new and useful Improvements in Combination Carpet and Window Cleaners,-of which the following is a specification.

This invention relates to a vacuum cleaner having combined therewith means for washin windows or the like.

he invention has for an object to provide a simple'arrangement of parts whereby the device may be used as an ordinary vacuum cleaner or sweeper, or may be utilized to wash windows, or any othersurfaces of relatively smooth configuration.

For further comprehension of the inven tion, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a horizontal sectional view of a device embodying the invention, this view being taken on the line 11 of Fig. 2.

Fig. 2 is a longitudinal sectional view, taken on the line 2-2 of Fig. 1.

Fig. 3 is a detail longitudinal sectional view on the line 33 of Fig. 1.

As here shown my improved combination cleaning device comprises a circular casing 10 in which is a variable speed electric motor 11-. In front of this casing 10 is an enclosed chamber 12 in which is a suction fan 13 driven by the motor 11 From this chamber 12 a short conduit 14 leads forwardly and downwardly to a transversely elongated, open-bottomed suction box 15. A yoked handle 16 is suitably hinged to the casin 10. The chamber 12 has an exhaust pipe 1% leading therefrom and adapted for connection to the usual bag. The device is supported b means ofa pair of front wheels 20, suita ly mounted in rearward offsets. 21

from the ends of the suction box 15, and a rear castor wheel 22 central under the easing 10. The device as thus described is arranged for use as an ordinary vacuum sweeper.

The window washing means is as follows: Fixed to the rear end of the shaft of motor 11 is a bevel gear 25 meshing with a like gear 26 on a transverse shaft 27 on which is rod 52 it is provided with a Specification of Letters Patent. Patented Apr. 11, 1922, Application filed October 7, 1921.

. axially to a roller 37 of rubber or the like,

having a rough peripheral surface arranged for detachable mounting in the suction box 15. As here shown this roller 37 has one trunnion 38 projecting through a suitable aperture in one end of the box 15, while the other trunnion 40 is supported in a short downward offset on the inner end of an .angular slot 41 leading upwardly through the end wall of the box 15 from the bottom thereof. To hold this last mentioned trunnion in place I provide on the end wall of a box 15 a vertically slidable plate 42 whose lower end is provided with a semi-circular notch engaging the trunnion 40. This plate 42 has formed therein vertical slot 43 into which project a pin 44 and a bolt 45 fixed to the end wall of the suction box 15. The bolt 45 has a nut 46 threaded therein and adapted to be screwed against the plate 42 to releasably hold the latter in lowered, or operative, position. By unscrewing nut 46 the plate 42 may be raised to allow the'trunnion 40 to be swung out of the slot 41 when the roller is to be removed.

I also preferably provide means whereby the roller is given an axial reciprocating movement and to this end the roller has an obliquely arranged peri heral groove 50 adjacent one end into which projects a finger 51 fixed to a rod 52 mounted in the box 15, behind the roller 37, for angular adjustment. As will be apparent, when roller 37 rotates, the engagement of the finger 51 in the groove 50 will impart an axial reciprocatory movement to the roller.

When it is not desired to impart a reciprocatory movement to the roller 37 rod 52 is rocked to free finger 51 from groove 50, and the roller is moved in one direction to its extreme position. Rod 52 is then further rocked until a second finger 54 thereon engages behind the end of the roller. To rock projecting head 55, and toholdit in either adjusted position it has fixed thereto a hooked sprin catch 56 adapted to engage in either one of 'a pair'of holes 57 in the end wall of box 15. When the roller is used a suitable cleaning powder sweeper or cleaner, the roller 37 is removed from the suction box and the device operated in the usual manner. When the device is 1n use as a window cleaner the handle 16 may be removed by springing the ends of its yoke off their attaching means, and a short fixed handle 60 may, be screwed into the back of the device.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows: 1. In a-device of the class described, a suction box, means for exerting a suction therethrough, a roller adapted for removable mounting in said suction box, and means for rotating said roller, and means for imparting an axial reciprocating movement thereto, said last means comprising a fixed element engaging in an oblique peripheral groove extending around the roller.

2. In a device of the class described, a suction box, aroller adapted for removable mounting in said suction box. and having an oblique peripheral groove extending therearound, means for rotating said roller, a rod in said suction box behind said roller and parallel thereto, and a pair oflongitudinally and angularly spaced fingers on said rod one of which is adapted to engage in said groove and the other to project across the end of the roller. K

3. In a device of the'class described, a suction box, a roller adapted for removable mounting in said suction box and having an oblique peripheral groove extending therearound, means for rotating said roller, a rod in said suction box behind said roller and parallel thereto, and a pair of longitudinally and angularly spaced fingers on said rod one of which is adapted to engage in said groove and the other to project across the end of the roller, and means for locking said rod in angularlyadjusted positions.

4. In a device of theclass described, a suction box, a roller adapted for removable mounting in said suction box and having an oblique peripheral groove extending theresignature. I V ARPAD POLANSKY.
